HOMOCYSTEINE LEVELS AND THE RISK OF OSTEOPOROTIC FRACTURE 1

The occurrence of osteoporotic fractures was correlated with homocysteine levels in 2406 subjects, 55 years of age or older. An increased homocysteine level was a strong and independent risk factor for osteoporotic fractures in older men and women, independent of bone mineral density and other potential risk factors for fracture.
HOMOCYSTINE MAY INTERFERE WITH COLLAGEN CROSS-LINKING 2
Healthy homocysteine levels can be
maintained with a combination of Folate,
B12 and B6
. The body-ready (conenzymated) form of these
vitamins may help overcome obstacles to metabolizing homocysteine.

Homocysteine may affect osteoporosis by interfering with collagen cross-linking, resulting in a defective bone matrix. Increased levels of homocysteine have been found in post-menopausal women, and the beneficial effect of folate supplementation appears to occur even in women who have no apparent deficiency of the vitamin.
HOMOCYSTEINE PREDICTS HIP FRACTURE 3

The association between the total homocysteine concentration and the risk of hip fracture in men and women enrolled in the Framingham Study was studied. The age-adjusted risk for hip fracture was four times higher for men and nearly twice as high for women in the group with 25% of the highest homocysteine readings (when compared to participants in the lowest quartile). These findings suggest that homocysteine concentration, which is easily modifiable by means of dietary intervention, is an important risk factor for hip fracture in older persons.
- Additional studies are needed to determine
whether folate intake or lowering homocysteine levels have
a consistent direct, causal role in preventing osteoporosis
or bone fractures.
